This item is a fake. I've encountered others, but this is the first on Amazon.There are others, so beware. It initially reports the proper storage size, then once written to it usually crashes. You can try to reformat it and it will not work. Stick to name brands.
Product worked fine until I unplugged it from my phone. It began to violently corrupt my data and then had connection issues with my PC. Had this for a little over a month. It seems that it has no protection against not ejecting safely. If you buy this product, be warned that you MUST eject safely. I had 20GB of files on mine and alot of them were corrupted. If you don't remove this product from your device or you are one of the few that safely eject, you will find it to be decent quality. For me however, I unfortunately will not be buying another one for fear of more data loss.
After giving this card a (not so) quick test with H2testw, I can confirm that it is 100% legit. It has the capacity as advertised, and is faster than 10MB/s (what the U1 standard requires). I only got this because I needed a spare card and something to fill out the free shipping amount, but this sure seems like overall a good card.
All of a sudden, my Garmin GPS was acting wonky. I watched multiple YouTube channels to figure out what was wrong. All of a sudden my self care fell out of the device and it worked perfectly. Upon more research, I found that the sd cards degrade over time due to the constant recording. The manual also states that they recommend that the card be changed once per year — it had be 2.5 years. I flew to my trusty amazon app and looked for a new card. These came quickly (actually before the estimated date) and they fit perfectly. The packaging looks slightly different than the picture but sd cards are pretty generic so I am not too worried about that.
I might have read the description wrong for this SD card but I tried to put it in my pixel 3XL and it didn't work so I'm assuming it's made for a computer or something so I'm still waiting to find something to put it in but otherwise it was what it was
